in this also, that under the older method the length of line spent is exclusively relied upon, while the spending of this length depends on other conditions also, besides the dept21 of water, while under the new method this cause of error is avoided, and a more reliable basis of conclusion is utilized, namely, that of vertical fall and time spent therein, which is regulated by a law of nature independently of all causes of error, as long as free fall is resisted by the water only and not by any action of the sounder.

Navigators testing the new method aside of the old will probably not hesitate to accept the new one. As in the use of the sextant, simultaneous observation with either similar or different leads will be a safeguard against error of observation.

And so precise and rapid is the sounding under the new method, that simultaneous sounding at bow and stern on an ocean steamer will at once tell the direction and degree of falling off in depth on the steamer's course.

Any communication on the subject from those practically versed in matters of navigation will be most' thankfully received by the author. I-IOBOK~N, N. J., March, x894.
